405nm Optical Bandpass Filter with FWHM 30nm

A 405nm optical bandpass filter with a Full Width at Half Maximum (FWHM) of 30nm is an advanced optical filter that selectively transmits light centered around 405nm while blocking or reducing light outside of this narrow wavelength range. This filter offers a broader bandwidth than typical 10nm filters, providing a wider range of transmitted light for applications that require slightly more flexibility in the spectrum.
